Imagine eating 12 pounds of food a day -- and still staying thin and healthy. That may sound crazy, but it’s exactly what our hunter-gatherer ancestors ate for millennia! And they didn't have any obesity or chronic diseases like heart disease, diabetes, cancer, or dementia.

Of course, I wouldn't advise anyone today to eat 12 pounds of food, because the food in our society lacks one major secret ingredient that our ancestors ate in nearly all their food -- fiber!

Fiber has so many health benefits that I want to focus on it in this week's blog. I’ll explain some of its benefits and give you 9 tips you can begin using today to get more fiber in your diet. I’ll also tell you about my favorite “super-fiber” that can help you increase your total fiber intake overnight.

But before I tell you about what fiber can do for you, let's a look a little more at the history of fiber.

Taking just a few vitamins CAN optimize the function of ALL your body's systems. It’s true. But you have to know what to take and you have to know why these supplements work ...

That’s why, in this week’s blog, I am going to discuss one of the most important biochemical processes for long-term health and how you can keep it running at its very best with supplements and other measures.

Unfortunately, many people suffer from one or more of the 8 factors that negatively impact this biochemical process, so problems in this area are widespread though many don’t realize they are suffering.

The good news is that there are MANY things that you can do right now to optimize this critical biochemical process that may have a dramatic impact on your health. In today’s blog I will review the 8 factors that can lead to problems in this area, and outline 12 tips that will help you optimize this essential part of your biology.

But first, I'd like to tell you about two of my patients with seemingly unrelated health problems that were actually caused by a breakdown in this biochemical process. And I want to share a study done on Chinese babies who had a birth defect known as spina bifida.

You'll be amazed at how all three -- my two patients and these Chinese babies -- were affected by the exact same thing ...

There is now a way you can boost your metabolism without changing how much you eat. It's true. You can rev up your metabolic engine, feel more satisfied when you eat, burn more calories, and lose more body fat -- all without even changing how MUCH you eat.

Recent studies show how three key changes can help you accomplish your weight loss goals without changing the amount you eat. They are:

1. Meal timing and meal frequency -- In other words, when you eat and how often.

2. Meal composition -– Specifically the role of protein in controlling appetite centers in your brain, increasing caloric burning, and reducing belly fat and weight.

3. Drinking green tea -- Which turns up your fat burning thermostat.

All three of these things have one very important concept in common: thermogenesis -- the creation of heat in your body. When you increase the thermogenesis in your body you literally turn up your metabolic fire.

Thermogenesis has nothing to do with the amount of calories you consume. It's controlled by a number of different interconnected control systems in the body designed to keep us healthy. By optimizing these systems you can turn up your metabolic fire without turning down the foods you love.

Today I will explain how the three key factors outlined above affect thermogenesis and give you a 5-step plan to increase your metabolic fire. Let's start by taking a look at the first thing that increases thermogenesis -- when and how often you eat.
